JOHN E. KEITH, OF CANTON, OHIO, ASSIGNOR, BY DIRECT .AND MESNEASSGNMENTS, TO THE NOVELTY CUTLERY COMPANY, OF CANTON, OHIO, ACORPORATION OF OHIO.

CHURN.

Application filed January 31, 1918.

To all whom t may concern Be it known that I, Jol-1N E. KEITH, a citizenof the United States, residing at Canton, in the county of Stark andState of Ohio, have invented a new and useful Churn, of which thefollowing is a specification.

This invention relates to churns and more especially to dashers forchurns, the object being to provide a dasher that will have a maximumsweep in agitating the mass within the churn.

With this object in view the invention consists in the novelconstruction and arrangement of parts, hereinafter described,illustrated in the accompanying drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size and minor details of construction may be madewithin the scope of the appended claims, without departing from thespirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a longitudinal sectional view through a churn with thedasher shaft and dasher shown in elevation and constructed in accordancewith my invention.

Fig. 2 is a perspective View on a somewhat enlarged scale of the churndasher and the lower portion of the dasher shaft connected thereto andconstructed in accordance with my invention.

Similar numerals of reference indicate corresponding parts throughoutthe several figures of the drawings.

At 1 is indicated a churn cylinder, which, in this instance takes theform of a glass jar with the threaded portion 2, upon which is fitted athreaded cap 3. Riveted to the said cap is a casting with uprightportions 1 and 5 and terminating in a hand grip or handle 6. Journaledin a bearing formed in the upright 5 is a shaft carrying a large beveledpinion 7, which shaft is adapted to be rotated by means of the crank 8and eX- tending inwardly from the upright 4 is a short arm terminatingin al rounded portion 9 through which is formed a vertical bearing forthe upper end of the dasher shaft 10 and secured to the dasher shaft andmeshing with the beveled pinion 7 is a relatively smaller pinion 11. Itis obvious from the foregoing that the Specification of Letters Patent.

rotation of the crank 8 will cause the dasher shaft 10 to be rotatedthrough the pinions 7 and 11. Secured to the dasher shaft 10 is a dasher12 which is formed of a sheet of metal or other suitable material and inblank is made in the form of a simple oblong piece. The corner 14 fromthe point 15 at approximately the vertical center at the right of theblank to the point 16 at he upper edge and slightly at the right of thehorizontal center is then stamped at a slight angle to the plane of thebody of the dasher and the opposite corner 17 from the point 18 at thevertical center at the left to the point 19 at the upper edge and spacedslightly to the left of the horizontal center is stamped insubstantially a parallel plane to the corner 14 thus throwing one cornerat an angle to one face of the dasher and the opposite corner at asimilar angle to the other face of the dasher. The lower corner 20 isalso stamped from the point 18 to the point 21. rThe last named pointbeing approximately the horizontal center of the bottom edge of thedasher. rlhe corner 20 is inclined in the same general direction as thecorner 17 that is, it is bent toward the same face of the dasher as thecorner 17. F rom the point 21 to the right hand side of the bottom ofthe dasher the edge is turned slightly in the same general direction asthe corners 17 and 2O forming a lower flange 22.

The dasher thus formed is then attached to the shaft 10 at a point atthe horizontal center' at the top edge of the oblong and with the rightlower corner 24 of the oblong in substantially an exact vertical linebeneath the center of the top edge. lt is obvious that this means ofattaching swings the majority of the dasher body to one side of itsaxis. The advantage gained by this construction will be apparent when itis pointed out that where the dasher body is symmetrical, orconcentrically arranged so to speak with the shaft with which itrotates, the greatest diameter of the dasher would be determined by thewidth of the opening to the cylinder body and as in the case of a glasscylinder body of the fruit jar type, in which the aperture through whichthe dasher must be inserted is approximately two-thirds of the greatestwidth of the jar, the dasher can only be made of suflicient diameter toagitate approximately two-thirds of the mass. It is obvious that adasher formed in accordance with my invention can be made to extend thefull radius between the aXis and the inner surface `of the jar or churnbarrel and thus cause the entire mass to be agitated, at the same timeallowing the said dasher to be easily inserted through the opening VatVthe top.

To operate the churn the crank 8 is designed to be rotated in thedirection that would bring the crank forwardly and then upwardly fromthe position shown in Fig. 1, which operation of the crank would causethe dasher shaft to be rotated in the direction of the arrow in thisfigure. Assuming that a mass, to be churned has been placed in thecylinder portion, the movement of the vdasher in 'the direction justdescribed willcause the in-turned corner-20130 begin movin-g the m-assinwardly from the lower right hand corner of the cylinder in Fig. 1. Asthe dasher is moved vthe vmass will be forced away from the side of thechurn by theouter edge of the corner 20 and will move upwardly on thetop face of the said in-turned corner toward the point '18, describing asubstantially spiral course. The upper in-turned corner 17 is meanwhilemoving substantially above the corner 2O but slightly nearer the aXisofthe dasher and is therefore spaced slightly from the side of the jarat this point'a-nd contacting as it moves, with the mass it forces itrst downwardly whence the saidmass comesin contact with a portion of themass being fed upwardly by the'cor'ner 2O as indicated by the arrows inFig. l, the two currents of the mass mergingl and 'being forced past thecorner 17 in the direction indicated by the arrows. The corner 111 whichis meanwhile rotating on the opposite side of the axis contacts with'the current of the mass passed over the corner 17 and because of theinclination of its under-face forces A"the mass downwardly toward thebottom of the cylinder where it will be caught bythe corner 20 on itsnext revolution and forced up wardly as previously described. The flange22 formed upon the bottom edge of the dasher from the corner 24: to thepoint 21 n is pitched at an angle to tend to force the 'mass downwardandto thoroughly-assistin agitating the entire Vsubst'ancebeing'cliurned.

From the foregoing it will be obvious that my dasher will obtain themaximum agitation possible in a churn of the given size and while it isespecially adapted for use upon churn barrels or cylinders with anopening of less diameter than the churn barrel itself it will be:clear-that it may be-also used upon churns with .parallel sides up toand through the point of entrance.V
